Auxins are plant hormones that coordinate several aspects of root growth and development. Indole-3-acetic acid (IAA) is an auxin

that is usually synthesized from the amino acid tryptophan (see figure to the right). The Trp-T gene encodes an enzyme that converts tryptophan to indole-3-pyruvic acid (I3PA), which is then converted to IAA by an enzyme encoded by the gene YUC. Predict how the deletion of one base pair in the fourth codon of the Trp-T gene would most likely affect the production of IAA. Justify your prediction.

Lynna [10]

Answer:

30 percent

Explanation:

Protein is essential in living organisms. They are the building blocks of life and help in the replacement and repair of work out tissues of the body. There are various sources of protein which are plant sources and animal sources.

Animal sources include land and aquatic animals.Sea Finfish, ocean catches, and fish-farming provide approximately 30

percent of animal protein sources consumed by humans in the world.

Which of the following statements is false? Sunlight is the energy source for plant photosynthesis. Chlorophyll is contained in
pentagon [3]
<span>Option 1: Sunlight is the energy source for plant photosynthesis.
True: In photosynthesis, plants convert light energy from the sun to chemical energy in the form of glucose. 

Option 2: Chlorophyll is contained in organelles called chloroplasts.
True: Chlorophyll in the chloroplasts is what allows many wavelengths of light for be absorbed and used for photosynthesis. 

Option 3: A by-product of photosynthesis is carbon dioxide.
False: Plants require carbon dioxide to create glucose, and produce oxygen as a by-product. 

Option 4: Roots have tiny root hairs that maximize the plant's ability to absorb water. 
True: Root hairs are very important for the absorption of nutrients and water by plant roots. </span><span /><span>

The average conversion energy from producers to primary consumers is a. 1% b. 10% C. 50% d. 100%​
KATRIN_1 [288]

Answer:

The average conversion energy from producers to primary consumers is b. 10%.

Explanation:

This percentage actually holds true for all transfer of energy at any trophic level in the food chain. Majority of the energy loss can be attributed to metabolic processes that give off heat and other forms of energy. It is important to note that energy cannot be created nor destroyed, it is simply transformed from one form to another.

One strand in a segment of a gene has the base sequence TGCTTA. What would be the complementary sequence of nucleotides found on
yarga [219]

The complementary sequence of nucleotides found on the other strand of DNA is <u>ACGAAT</u> when one strand in a segment of a gene has the base sequence TGCTTA.

<u>Explanation:</u>

Deoxyribonucleic acid is the one which carries the genetic information from the parent to the offspring.  During DNA replication one strand of DNA replicates to produce another strand.        

The DNA molecule have a anti-parallel structure and the two strands run in opposite direction. If in one strand in a segment of a gene has the base sequence TGCTTA the complementary sequence of nucleotides found on the other strand of DNA will be ACGAAT.

Compare photosynthesis and respiration with regard to each of the following
docker41 [41]

Answer:

Explanation:

Photosynthesis Vs. Respiration

1) Photosynthesis gets it's energy from sunlight, and uses the sunlight to change water and CO2 into energy. Cellular respiration gets it's energy from glucose molecules and oxygen.

2) Photosynthesis uses energy, CO2, and water to make energy and releases oxygen. Cellular respiration uses glucose molecules and oxygen to make energy, and releases CO2 and water.

3) Cellular respiration takes place in the mitochondria, and photosynthesis takes place in chloroplasts.
